floating-hub type, an object bein to provide a wheel which will absorb shoe Other objects and advantages of the invention will be set forth .in the ensuing deseri'ption. 4

(The drawings show one of the practical forms in which the. invention may be embodied. t

Figure 1 is an elevation iew of the wheel with portions broken away to expose interior construction.

Fig. 2 is a similar view of a portion of the wheel, but with parts in different relative position.

"Fig. 3, is asimilar view of the full wheel, but .withthe parts in still another position. Fig. 4.- is a cross-section view of theouter portion of the wheelon larger scale.

In Fig. 4 all parts which are connected togetherand move together are shaded in the same direction, with the exception of an extreme outer thread material on which the shading is clouded, and two packing cords which are shaded in solid black.

Like characters of reference designate like parts in all the figures. p

In carrying out the objects stated, the improved: wheel comprises two principal portionsan outer or thread portion whose inner surface is channeled, and an inner portion whose outer edge fits movably within the channel of the outer portion.

The diameter of the inner portion of the wheel is such that a space of, say, one-half inch in a thirty-four-ineh wheel is left between its outer periphery and the bottom of the channel of the outer portion, thus allowing the inner portion one-half inch eccentric movement from normal central position during revolving movement of the wheel;

of the inner portion of the wheel downward in the channel of the outer portion tends to, and does, crowd the oil around in the channel in the direction of the arrows 11.

, The oil. or other substance used in the channel should be of such character or consistency that while it will slowly yield to the presure of a light load on the inner portion of the wheel it will not too quickly yield to a heavy load. The'oil will then act to absorb any shock brought upon the wheel by the load.

, In the wheel shown in the present instance the outer part of the outer channeled pol; t1on consists of a strap-metal hoop 12 whose edges are flanged outwardly as at 13, the space between these flanges being filled with a suitable tread material .14. l. l p

Asbest-shown in Fig. 4, the channel in the outer portion ofthe wheel is formed by a channel-iron ring 15 whoseouter or back portion 16 is brazed to the outer hoop 12,

the side walls 17 of this channeled ring projecting inward as shown.

The central portion of the Wheel includes the usual hub 18; spokes 19; felly 20; and channeliron rim 21 which may be shrunk onto said felly as usual.

The outer edge of the inner portion of the wheel, which is arranged to fit inthe channeled ring 15 of the outer portion consists of a channel-iron ring 22, the inner: edges of whose side walls 23 are brazed to the channel-iron rim 21. 3 p i The space 24 left between the two channel-iron rings 15 and 22 is filled with the oil 25 above mentioned.

In further completing the wheel, an inwardly-extending wall 26 is brazed to each side of the extreme outer hoop 12 and extends with an oil-tight fit into the channeliron rim 21 of the inner portion of the Wheel, the side walls 27 of said rim 21 being grooved on their inner surfaces as at 28 and having said grooves filled with packing cord 29.

The channeled rim 21 may be provided with inner walls 30 in addition to its side walls 27, so that the walls 26 of the outer hoop 12 may slip between said walls 27 and 30 with a more oil-tight fit.

The channeled ring 15 may have its side walls 17 braced to the outer hoop portion 12 by bracing rings 31 which are brazed in place.

In order that the inner portion of the wheel shall not revolve in the outer portion when driving or braking force is applied,

- the outer surface of the inner portion is scalloped or corrugated as at 32, as is also the ner por'tion of the wheel "rests down onthe lower side of the outer portion, openings d lid n re sfi tw iif .1 bottom Iortrough portions of-the corrugations32 of saidinner'portionand the trui circular inner edg e i35of the "channel-iron ring 15; so that by suction the oil the space 24 asthe wheelrevolvesf tion having a channel; in its; inn p Havingthusdescribe'd the invention, Claim:- r a 1.
